Product introduction

NR-PD Precision DC voltage divider adopts for national- wide, provincial and municipal Quality & Technical Supervision, high voltage laboratory as standard divider. As it’s with high accuracy, that could measure DC relative small changes, and provide reliable measurements  for analyzing varies of materials, precision measuring voltage and nominal voltage.
NANRUI Electrical have committed to promote precise DC voltage divider, so far the highest voltage level is 500kV, the highest accuracy is 0.05%.Fully listening to the views of provincial Metrology Institutes, we have resigned this series of products, which make it lighter and stability. All the core components were imported, through a more than 30 kinds of strict screening processes, guarantee the excellent performance.

Product information

Five series dividers used for High voltage measurement, the difference are in uses object and major function:
1.FRC Series AC-DC voltage divider used for measuring the power frequency which the accuracy is less than 0.5%, AC high voltage under 300Hz, and DC high voltage which the accuracy is less than 0.5%. Widely used in national wide and city level power supply bureau, power plant, varies of electrical installation company and power maintenance unit of large power enterprise.
2.NRPD Series Precision DC divider used for DC voltage precision measuring which the  accuracy demand is 0.2 %, 0.1% and 0.05 %.Such as the national wide and city level municipal pilot station, metering stations and research institutes .
3.NRPA Series Precision DC divider used for DC voltage precision measuring which the  accuracy demand is 0.2 %, 0.1% and 0.05 %, and the frequency is 30-300Hz. Applying to high-voltage cable dielectric loss testing by national cable manufacturers, and as a power frequency standard in provinces & municipal pilot station and electricity metering station, while measuring 30-300Hz AC high voltage.
4.NRV series high frequency divider measuring frequencies up to 1M-10M or more , the DC measurement accuracy is <0.1%, 10Hz-1MHz pulse pressure measurement accuracy is <1.0%, 1MHz above measurement accuracy < 3%. Suitable for analyzing the high-voltage circuit breakers, high voltage DC power supply , particle accelerator and  a variety of high-voltage high-frequency characteristics with an oscilloscope connection.
5.NRP series pulses divider use for measuring variety of standard light wave, the response time is less than 100ns.
6.Nanrui (NR) dividers naming rules as follows :
FRC-General divider series ( also known as SGB digital high voltage meter ) , mainly  measuring for frequency voltage , is inaccurate, just satisfy the general measurement requirements
NR-representative for Wuhan NANRUI Electric Co.;
P-is the first letter of precision, used for precision high voltage measurement
D-is DC, used for measuring DC voltage;
A-is AC, used to measuring AC voltage;
HF-is high and the frequency of the first letters used to measure high frequency voltage
P- is pulse, used for measuring the pulse voltage.
Ordering Information:
FRC series voltage divided into three kinds products based on different types of measurements
1, FRC capacitive divider (FRC said measuring AC also called AC voltage divider);
2, FRC RC divider (or called FRC AC and DC voltage divider that can measure AC and DC);
3, FRC resistor divider (or called FRC DC voltage divider for measuring DC)
If do not indicate the type, it defaults to AC and DC voltage divider
